Bombardier Aerospace reported at its European Regional Review in Munich, Germany that prior to the airliner’s entry-into-service, it is targeting CSeries aircraft line maintenance checks (“A Checks) at intervals of 850 flight hours and base maintenance checks (“C” Checks) at intervals of 8,500 flight hours. Bombardier has been developing a Maintenance Steering Group 3 (MSG-3)-based maintenance program since October 2010 for the CSeries aircraft. Throughout the design evolution phase, the company has determined that line maintenance and base maintenance task intervals at, or in excess of, 850 and 8,500 flight hours respectively, can be achieved. The proposed maintenance plan will allow operators of CSeries aircraft to benefit from minimized downtime and more competitive maintenance costs, all while ensuring the inherent safety and reliability of the aircraft. The maintenance program for the CSeries aircraft remains under development using the MSG-3 process where analysis for systems, powerplant and structures are reviewed during working groups and approved by the CSeries aircraft Industry Steering Committee (ISC). Bombardier currently has multiple working group and ISC meetings prior to submitting the Maintenance Review Board Report to the Authorities for acceptance, prior to entry-into-service in 2014.
